WebSep 4, 2024 · The Lie derivative of the Christoffel symbol is L ξ Γ i j k = ∇ i ∇ j ξ k − R i j l k ξ l. How can one prove that? And why does it make sense, because Christoffel symbols are functions? I know that the last question could be irrelevant, since the correct form of the LHS of the equation should be ( L ξ Γ) i j k. But, I still cannot figure it out. phorms lunchWebMar 2, 2024 · The second way is more straightforward and less clever: Do the variation and do the calculation explicitly, using the expression of the Christoffel symbol (1), and plough ahead. I've written down the calculation in terms of ; you should be able to convert that to by using the inverse relations, i.e. varying. Last edited: Jun 24, 2016. how does a horse costThe Christoffel symbols can be derived from the vanishing of the covariant derivative of the metric tensor gik : As a shorthand notation, the nabla symbol and the partial derivative symbols are frequently dropped, and instead a semicolon and a comma are used to set off the index that is being used for the derivative.
